LEONARD T. STRAND, District Judge.
This matter is before me on a Report and Recommendation (R&R) which recommends that I accept defendant's plea of guilty. See Doc. No. 37.
On September 23, 2015, defendant was charged in a one-count indictment. Count 1 charges defendant with knowingly possessing and attempting to possess visual depictions of minors engaged in sexually explicit conduct, including a depiction involving a prepubescent minor or a minor who had not attained 12 years of age, said visual depictions having been produced using materials that had previously been shipped and transported in and affecting interstate and foreign commerce, namely, a Samsung cellular phone, manufactured outside the state of Iowa, and said visual depictions having been transported in and affecting interstate and foreign commerce and using a means and facility of interstate and foreign commerce in violation of 18 U.S.C. §§ 2252A(a)(5)(B) and 2252A(b)(2). On February 26, 2016, defendant appeared before the Honorable C.J. Williams, United States Magistrate Judge, and pled guilty to Count 1 of the indictment. On the same date, Judge Williams filed an R&R in which he recommends that defendant's guilty plea be accepted. The parties have waived the right to object to the R&R and have consented to its acceptance. See Doc. No. 38.
A district judge must review a magistrate judge's R&R under the following standards:
28 U.S.C. § 636(b)(1); see also Fed. R. Civ. P. 72(b). Thus, when a party objects to any portion of an R&R, the district judge must undertake a de novo review of that portion.
Any portions of an R&R to which no objections have been made must be reviewed under at least a "clearly erroneous" standard. See, e.g., Grinder v. Gammon, 73 F.3d 793, 795 (8th Cir. 1996) (noting that when no objections are filed "[the district court judge] would only have to review the findings of the magistrate judge for clear error"). As the Supreme Court has explained, "[a] finding is `clearly erroneous' when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed." Anderson v. City of Bessemer City, 470 U.S. 564, 573-74 (1985) (quoting United States v. U.S. Gypsum Co., 333 U.S. 364, 395 (1948)). However, a district judge may elect to review an R&R under a more-exacting standard even if no objections are filed:
Thomas v. Arn, 474 U.S. 140, 150 (1985).
Because neither party objects to the R&R, I have reviewed it for clear error. Based on that review, I am not "left with the definite and firm conviction that a mistake has been committed." Anderson, 470 U.S. at 573-74. As such, I hereby
